Hybrid Relay-Reflecting Intelligent Surface-Assisted Wireless Communications

Nhan Thanh Nguyen et al.

Summary: Reconfigurable intelligent surface (RIS) is a cost- and energy-efficient solution to enhance wireless communications capacity, but its performance is limited by the surface size and hardware impairments. To overcome these challenges, we propose a hybrid relay-reflecting intelligent surface (HR-RIS) architecture and design corresponding beamforming and relay-reflection strategies. Simulation results show that HR-RIS can significantly improve spectral and energy efficiency, and outperform conventional relaying scheme in most cases.
